Hi,
I inspected the files and found something problematic.
I wanted to say you needed ExLink cable for start up this.
Patch requires a start script at USB. Instead, why we don't push it to exe.img?
This will require little work or me. Until you can download files from here and patch your image by hand.

Instructions:
*Download the original firmware from samsung.
( http://downloadcenter.samsung.com/conte ... RBYDEU.exe )
*Extract downlaoded file.
*mount exe.img as FAT and change start.sh file at root with provided one. (Requires linux)
*Flash your TV with modified firmware.
*Copy USB directory contents to your USB's root.
*Turn On your TV while USB is plugged.

Hi erdem_ua,

I'm back and can add information on patching LNXXA850 (T-SPHAUSC) to the above mentioned page. Please give me editing permissions. Patching SPHAUSC is much simpler. Image is not encoded at all and can be edited with squashs tools. Telnetd exists and does not require injection of new busybox. There are two ways to enable it: either editing startup script in exe.img file or by using modified samygo extension. I have described both methods here: http://forum.samygo.tv/viewtopic.php?f=2&t=202 and here:
http://forum.samygo.tv/viewtopic.php?f=4&t=207

Actually I can share my patched firmware (v.1004) which auto starts telnetd, so generation of patch script using original and modified firmware should be easy.

BTW. Notes on http://samygo.sourceforge.net/ page about T-SPHAUSC are incorrect. Busybox injection is not needed and as I said earlier starting Telnetd is possible with both methods.
